When was the Manchester to Liverpool Railway built?

The inaugural train of the Liverpool and Manchester Railway travelled on 15th September, 1830, drawn by the locomotive 'Northumbrian'. It carried many notable people including the then Prime Minister, the Duke of Wellington. Another passenger was William Huskisson, member of Parliament for Liverpool. When the train stopped at Parkside for other locomotives to pass in review on the other line, Huskisson was run over by the locomotive 'Rocket' (which had won the Rainhill trials for Robert Stephenson), and died of his injuries later the same day. A memorial to him still stands by the line. The Liverpool and Manchester railway was the first public transport system wholly to use steam power.
